Estimate solar incentives, solar tax credits, state rebates, utility rebates, performance incentives, SREC-style credits, net solar cost, payback period, lifetime savings, and solar ROI. Use this calculator to compare gross solar cost against possible incentives and long-term savings.
Simple mode:
The calculator estimates a federal credit, subtracts rebates, and shows net project cost after incentives.
Stacked incentives mode:
The calculator combines federal credit, state rebate, utility rebate, property tax value, sales tax savings, and other incentives.
Performance mode:
The calculator estimates production-based incentives using annual solar kWh, incentive rate, incentive years, and SREC-style certificate value.
Net cost mode:
The calculator estimates total incentives, net cost, annual savings, payback period, lifetime savings, and solar ROI.
A solar incentive calculator helps estimate how credits, rebates, and performance-based incentives may reduce the effective cost of a solar project.
It can help compare gross cost, federal credit, state rebate, utility rebate, per-watt rebate, production incentive, SREC value, net cost, payback period, and ROI.
Your result shows estimated total solar incentives, federal credit amount, usable credit this year, possible unused credit, state rebate, utility rebate, performance incentive value, SREC-style value, net cost after incentives, annual savings, payback period, lifetime net savings, and solar ROI.
A solar incentive is a credit, rebate, payment, exemption, or production-based benefit that may reduce the cost of installing or operating a solar system.
Add applicable credits, rebates, utility incentives, performance payments, SREC-style certificate value, tax savings, and other incentives. Then subtract them from the gross project cost to estimate net cost.
Some credits may depend on tax liability. The calculator separates the credit amount from the estimated amount usable this year based on the tax liability you enter.
A performance incentive is based on solar energy production, usually calculated from kWh generated over a set number of years.
No. This is an estimate. Incentives can vary by location, utility, income rules, project type, tax liability, ownership, installation date, program funding, and current law. Confirm incentive details before making financial decisions.
